My fiance has kindle. He is a reader and he LOVES it. I know some people say "why would I get this when I can go to the library for free?" Well, maybe your library is better than ours, but a lot of the time the books will be checked out. Or, if it's in a series, they will only have 2 or 3 of the series and not be consecutive (say their are 5 books in a series, they will only have books 1 and 3 or something like that). Amazon also offers books for download for free. The kindle also suggests books that you might like based off what you've downloaded.
It reads like paper. There is no glare. The battery life lasts for days without recharging. you just put it into sleep mode and it doesn't waste any battery while not reading.
